Answer 1

我正在阅读您的问题，询问如何仅在锦标赛结束后打印赢/输数字。要完成此操作，请在您的 while 循环之后移动您的最终 printf 语句。然后它只会在您的锦标赛结束后运行一次。

while (!tournament.equals("End of tournaments")) {
    int matches = Integer.parseInt(scanner.nextLine());
    receptacle += matches;

    for (int i = 0; i < matches; i++) {//TODO redact of needed to 0 and <
        int points1 = Integer.parseInt(scanner.nextLine());
        int points2 = Integer.parseInt(scanner.nextLine());

        if (points1 > points2) {
            won++;
            System.out.printf("%nGame %d of tournament %s: win with %d points.", i, tournament, points1 - points2);
        } else {
            lost++;
            System.out.printf("%nGame %d of tournament %s: lost with %d points.", i, tournament, points2 - points1);
        }

    }

    // Location of line to move from
    tournament = scanner.nextLine();

}
// Location of print statment to move to
System.out.printf("%n%.2f%% matches win%n" +
        "%.2f%% matches lost", (won / receptacle) * 100, (lost / receptacle) * 100); // As far as I'm concerned printing it outside of the loop using if statement doesnt't seem to work because the condition within is always true.
